01 - Line an 8-inch square baking pan with parchment paper, leaving an overhang on two sides for easy removal.
02 - In a small saucepan, combine the diced strawberries, granulated sugar, and lemon juice. Simmer over medium heat for 5 to 7 minutes, stirring occasionally, until the berries break down and the mixture thickens slightly. Set aside to cool completely.
03 - In a microwave-safe bowl, combine the chopped white chocolate, sweetened condensed milk, and unsalted butter. Microwave in 30-second intervals, stirring thoroughly between each interval, until the mixture is completely melted and smooth.
04 - Stir the pure vanilla extract into the melted fudge mixture until evenly incorporated.
05 - Pour the fudge mixture into the prepared baking pan, using a spatula to smooth the surface into an even layer.
06 - In a small bowl, beat together the softened cream cheese, powdered sugar, and heavy cream using a whisk or hand mixer until smooth and creamy.
07 - Spoon small dollops of the cooled strawberry compote and cream cheese mixture over the fudge layer. Use a toothpick or knife to gently swirl the toppings through the fudge, creating a marbled pattern.
08 - Refrigerate the fudge for at least 2 hours, or until completely firm and set.
09 - Lift the fudge from the pan using the parchment paper overhang. Cut into 16 even squares and serve chilled.
